Am I one of few people who is frightened by shell history files? I always disable mine because it just seems like a roadmap to interesting stuff for anyone who might gain access to it. Including even stuff like sudo passwords typed at the wrong time or into the wrong window.

The terminal backlog is just sitting in memory as well. Just don’t leave passwords there, remove them immediately. You also have an option not to save the command in history, e.g. whitespace prefix in bash. Half of my bash commands that are longer than 20 symbols start with ^R to look up a similar command and edit it, not having history would make that much slower.

Sure. But, you could auto-encrypt your ~/.bash_history if you're concerned about it being a problem and might need it for backtracing any issues etc?
